Se presentan los resultados obtenidos con dos técnicas endoscópicas, la punción aspirativa transbronquial y el lavado broncoalveolar (LBA) en el diagnóstico de 200 pacientes con cancer de pulmón.

Los pacientes fueron divididos en cinco grupos según sus características fibrobroncoscópicas (FB): 1) Con FB normal. 2) Con compresión extrínseca de la mucosa. 3) Con inflamación localizada de la misma. 4) Con infiltración difusa. 5) Con tumoración endobronquial. En todos los pacientes se intentó realizar biopsia bronquial (BBR), punción aspirativa bronquial (PAT) y broncoaspirado difuso (BAS). En los pacientes con FB normal se realizó biopsia transbronquial (BTB) bajo control radiológico y se practicó LBA. La sensibilidad de cada técnica fue evaluada mediante el test de McNemar.

En los pacientes de los grupos 1, 4 y 5, la PAT aportó pocos beneficios suplementarios a las técnicas habituales (BTB, BBR y BAS), sin embargo en los dos grupos restantes sus resultados fueron superiores. El LBA no aportó ventajas significativas al diagnóstico del cancer pulmonar periférico.

The results of two endoscopic procedures, transbronchial aspiration (TBA) and bronchoalveolar lavage (BAL), for the diagnosis of 200 patients with lung cancer (LC) are reported.

The patients were divided in fíve groups depending on their fibrobronchoscopic (FB) features: 1) Normal FB. 2) Extrinsic mucosal compression. 3) Localized mucosal inflammation. 4) Diffuse mucosal infíltration. 5) Endobronchial tumor. In all patients bronchial biopsy (BB), transbronchial aspiration and diffuse bronchoaspiration (BA) were attempted. In the patients with normal FB, transbronchial biopsy (TBB) under radiologic control and bronchoalveolar lavage were carried out. The sensitivity of each procedure was evaluated with the McNemar's test.

In patients from the groups 1, 4 and 5, TBA gave few additional information to data from the usual procedures (TBB, BB and BA); however, its results were better in the two remaining patient groups. BAL did not provide significant advantages for the diagnosis of peripheral lung cancer.
